Harley XL883R by Shaw Speed

Like Gulf Oil, Martini is a brand inextricably associated with speed. The blue and red stripes are one of the most distinctive liveries in motorsport, and forever associated with the Martini Racing Porsches from the 1970s.

Martini hits its 150th anniversary in 2013, and the English shop Shaw Speed & Custom has joined the celebrations by creating a pair of hot-rodded Harley Sportster XL883Rs—one in white, and one in silver, as shown here.

Each bike has a rebuilt motor with a tuned Screamin’ Eagle 1200 conversion, race-spec heads and pistons, and a custom-fabbed exhaust system. The forks have been fitted with Öhlins internals and finished in gold to match the rear shocks.

A lean Roland Sands Design gas tank and RSD bars add a little attitude, and the stock XL883R brake rotors have been replaced with larger versions fore and aft, beefing up stopping power.

The original fender rails have gone, with the frames modified to accept kicked-up rear fenders. The wheels are also custom built, with modified Dyna rims taking 180mm tires at the rear.
